NSK Case Study
Application
Wire Guides
Cost Savings: $10,718
A wire manufacturer was experiencing frequent damage on final products due to bearing failures within their wire guides. Deep Groove Ball Bearings were used in the application and were failing on average every six weeks, resulting in unplanned maintenance time and loss of production. It was determined failure was a result of an ingress of contamination behind the bearing seals. NSK recommended replacement of the existing bearing with Stainless Steel Deep Groove Ball bearings equipped with double contact DDU seals and Molded-Oil™ Lubrication.
